I am trying to create a sample flask app by following this tutorial https://realpython.com/blog/python/flask-by-example-part-1-project-setup/

但是自从我在运行于10.11.1的新Mac上设置Python和相关技术以来，我一直遇到一些问题.

But I am running into constant issues since I am setting up Python and related technologies on this new Mac running on 10.11.1

我被卡在输入此命令的地方

推荐答案

您不应该使用系统版本的Python.

You shouldn't be using your system's version of Python.

根据 Python的文档:

OS X随附的Python版本非常适合学习，但不利于开发.

The version of Python that ships with OS X is great for learning but it’s not good for development.

根据 Apple的文档:

鼓励使用Perl，Python，Ruby或OS X附带的任何其他脚本语言的开发人员管理他们自己的语言和依赖项安装...

Developers using Perl, Python, Ruby, or any other scripting languages that ship with OS X, are encouraged to manage their own installations of the language and dependencies ...

因此，我建议按照 Python的OS X安装文档.

请注意，这些说明提供了安装Python 2的命令.要安装Python 3，请运行:

Note that these instructions provide the command to install Python 2. To install Python 3, you would run:

brew install python3    # instead of 'brew install python'

这些Python安装文档还链接到安装virtualenv的详细说明，并virtualenvwrapper .

These Python installation docs also link to detailed instructions for installing virtualenv and virtualenvwrapper.

更新:

看起来您已安装virtualenvwrapper，但配置不正确.安装后，我根据 virtualenvwrapper 的安装文档运行了以下代码，以进行配置:

It looks like you have virtualenvwrapper installed, but not properly configured. When I installed it, I ran the following code based on installation docs for virtualenvwrapper to configure:

# Create a directory to hold the virtual environments.
mkdir $HOME/.virtualenvs

echo "
# Python's virtualenvwrapper-RELATED
export WORKON_HOME=$HOME/.virtualenvs
source /usr/local/bin/virtualenvwrapper.sh 
" >> ~/.bash_profile
source ~/.bash_profile
